ShibV4-LdapCognito Issue

[leosimon]

I have configured Shibboleth V4 with LDAP Auth for SP AWS Cognito. For
testing, call back urls are given as https://google.com. I can see from
idp-process.log and confirm that service running fine and metadata pulled
from remote but when I visit the SP URL and click on login, it just returns
with the URL as and no logs captured in the server.

https://www.google.com/?error=server_error

At the same time, I can get the results from cli using this,

bin/aacli.sh --url https://idp.example.com/idp --requester
urn:amazon:cognito:sp:exmapleURNofSP --principal leosimon
--changed the url as example.

I am completely blank and unable to proceed further, Can someone help me
where the error would me and what I might missed?
